CIRCULAR ORE-STAMP BATTERY.

SPECIFICATION forming part of Letters Patent No. 334,675, dated January 19, 1886,

Application filed May 22, 1885. Serial No. 166,348. (No mod 1.)

To all whom it may concern:

Be it known that I, ALMARIN' B. PAUL, a citizen of the United States, residing'in the city and count-y of San Francisco, in the State of California, have invented certain new and useful Improvements in Circular Ore-Stamp Batteries; and I do hereby declare that the following is a full, clear, and exact descrip tion of the same, reference being had to the accompanying drawings.

My invention relates to improvements in stamp mills or batteries of the circular kind, in the frames of which the stamp'stems are supported and guided. In batteries of this class the stamps are lifted and dropped by the action of a revolving horizontal cam against the under sides of the stamp-tappets, which are arranged in a circle around the periphery of the cam-disk,so that as the cam travels around the stamps are raised and dropped in succession. The stamp-stems have bearings in guides or boxes in the frame, that is set over the battery-motor, and of which the motor forms the bed or base. The parts of the frame therefore require not only to be firm and solid,'but to resist all tendency to spring and disturb the lines of the stamp-guides, and to such end to have their perpendicular lines of support disposed in a manner best calculated to maintain the true position of the stem-boxes, one over the other, under all conditions of the great strain and vibration to which the whole structure is subjected.

My invention consists in an improved construction of frame or support for the stampstems and in certain other features,as fully set forth in the following claims and description, in which latter reference is made by figures and letters to the accompanying drawings.

Figure 1 is an elevation of the mill set up for work. Fig. 2 is an elevation of the bed and frame above. Fig. 3 is a broken vertical sectionalview of one side of the machine.

Fig. 4'is a section of the upper plate or ring. Fig. 5 is a section of the lower plate or ring, showing the cam and gear under it. Fig. 6 is a plan view of the lower ring or plate.

The columns A A are set perpendicularly, and at the base are firmly secured to the rim of the mortar X. Upon their upper ends they support a circular plate, B, formed of a solid bottom, b, a cylindrical rim, B**, and a projecting flange, B b, with a central opening that fits close to the hub of the mortar. This plate is fixedto the top ends of the columns A by bolts a a a. It forms the bed or support for a set of shorter columns, A A also set perpendicularly like the principal columns, but nearer to the center. The horizontal flange 13* of this plate is cutaway between the. lines of columns to form openings 0 for the stamp-stems to play in, and the solid portions left form arms or extensions setting out radially and horizontally from the rim The rim isa circle or broad ring projecting from and cast solid with the bottom plate, and is of such diameter as to fit just within the circle of stamp-stems. The foot of each upper column A rests upon the extension of flange B* and just back of the line of the principal column, and each column sets against and is bolted to the ring B. The top of the frame is a circular plate, F, set on shoulders f, produced by setting off the top ends of the columns and having the columns bolted to it.

The two rings B F are of equal diameter, and the stamp-stems set against them are held by the boxes 9 9*, which are fixed by screws h to the rings, so that they can be renewed when worn and set to take up wear. In the center of the upper plate, F, is a bearing, H, for the upright shaft H* of the cam G, to which rotary motion is given from the driving-shaft I. The power is applied to the periphery of the cam or beneath it to the shaft H*, for which purpose the cam is cast with a bevel-gear, (3*, on the bottom, and the driving-shaft is geared into it by a bevel-pinion, I*; or a large gear is set beneath it upon the shaft H This construction brings the driving-shaft down to the lower and more stable part of the frame, as well as in close relation and more direct line with the resistance than where the power is applied to the top of the cam-shaft, as heretoforein other constructions.

I do not claim the cam and ment as shown, as such are old.

The spaces between the lower columns are closed by the screens W, and the sides w of the battery are fitted and fastened in place in the usual manner. The openings 0 around the top are covered with loose segment-plates gear arrange- L, as indicated in dotted lines in Fig. 6, and the solid center b of the plate B closes in the top of the battery.

From a comparison of these features of construction with those of circular batteries now in existence it will be seen that my improvements consist in the solid bed-plate secured upon the top of the battery, with the ring for the stamp-stems boxes or guides in one solid piece with it, and the ring for the upper guides, having for supports the upright columns, resting on and firmly screwed to the lower boxplate and bed-plate.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a circular ore-stamp battery, the combination of the battery-frame X A, the bedguides, the cam G, and the driving-gear G*, 30

the shaft I, and the pinion 1*, as set forth.

Vitness my hand and seal.
